To Connect the Module

The Logic Signal Output Module is an optional accessory of the DG3000 Series

Function/Arbitrary Waveform Generator. Connect the module to a DG3000 as

shown in Figure 1-5. Make sure that the power is off before and during the

connection. Power up the instrument, the DG3000 will confirm if the module has

been successfully installed by displaying the message: “Digital module is installed”.

Otherwise, repeat the above setup process until the screen shows the success

message.

DG3000 provides a switch function to control the power modes of the module.

Press Utility Output Setup Digit-Modu, as shown in Figure 1-6, there are

two power states: “Power-On” and “Power-Off”.

The module supports two work modes: “Depend” and “Independ”.

At the “Depend” mode, all the analog waveforms output are disabled, the output

rate and phase of digital output will have not limit.

At the “Independ” mode, both the module and DG3000 can works normally.

However, the output rate and phase of module will have “some limit” (See the

following prompt message).

The PO protocol setting menu and operation description are shown in the following

figure and table.


Keypoints:

Mask Channel

Data in the Mask Channel can be edited in the user space. “0” in the Mask

Channel, indicates the corresponding Tri-state Channel output is not high Z

(normal output), while “1” indicates the corresponding Tri-state Channel

output is high Z.

Tri-state Channel

Tri-state Channel is the channel to be “masked”. The Tri-state Channel output

depends on the corresponding data “1” and “0” in Mask Channel, high Z, and

not high Z respectively.

Example:

Suppose D0 is the Mask Channel, D1 and D5 are Tri-state Channels. Set data in the

three channels as shown below:

D0: 1 0 0 1 1 0 0 1 0 1 0 1 0 1 0 0 0 0 1 0 0 1 0 0 …

D1: 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 …

NOTE Only one of the channels (D0~D15) can be chosen as the Mask Channel.

The selected channel turns azury on the screen (See page 2-41, Figure 2-45 Channel marks).

Users can choose one or more channel as the Tri-state Channel. The selected channels turn bolarious on the screen (See page 2-41, Figure 2-45 Channel marks).

Both the opening (yellow on the screen) and the closed (white on the screen) channels can be chosen as the Mask Channel or the Tri-state Channel. The difference is that the opening channel can output but not the closed channel. To know how to open or close the channel, see page 2-42, Table 2-12(1) Operation menu description.

Output User Data

When Code Pat is set to “User”, the protocol will output the user-defined data, and

users can set the value of “Offset” to select the start data location.

The communication protocols have specified transmission sequence of data. For

example, RS232 uses “LSB”; SPI and IIC use “MSB”, but for PO, both “LSB” and

“MSB” can be used. Therefore, the output sequence of user data depends on the

choosen protocol.

LSB:

Least Significant Bit, for binary sequence 00001111, LSB is the most right bit “1”.

MSB:

Most Significant Bit, for binary sequence 00001111, MSB is the most left bit “0”.

In the following Example 1 and Example 2 we will introduce how to output

user-defined data.

Figure 2-26 Output user data

Example 1:

Use RS232 protocol, output data length=1 Byte, data line=D1, Offset=1, the other

parameters use default value, output user data as shown in Figure 2-26.

Explanation:

Offset=1 indicates the first data “1840” would not be output. As data transmitting

through line D1, it will output 8 bits (1 Byte) in the 8 data start from “044A”. The

data storage is shown in the following table.

Output:

1. According to the above table, the output data would be: 1 1 0 0 0 0 1 0;

2. For RS232 protocol, the output sequence is “LSB”, then the output should be:

0 1 0 0 0 0 1 1；

3. For RS232 protocol is negative logic output, in the output figure, “0” is

represented by high level and “1” is represented by low level as shown in the

figure below:

0 1 0 0 0 0 1 1

Note: For RS232 protocol, -15V～-5V is logic “1” and +5V～+15V is logic “0”.

Example 2:

Use PO protocol, output data length=4Bytes, data line=All, Offset=0, the other

parameters use default value, output user data as shown in Figure 2-26.

Explanation:

Offset=0 indicates the first data “1840” would be output. As data transmitting

parallel from the 16 channels, each channel will output 2 bits (total is 32 bits=4

Bytes). The data storage is shown in the following table.

Baud rate: Code elements transmission per second. The unit is Bps (Bauds per second).

Bit rate: Binary bits transmission per second. The unit is bps (bits per second). Bit rate is an important specification of digital communication system. When the channel is fixed, the higher the information transmission rate is, the better the effectiveness will be.

the PO Protocol

Operation steps:

1. Refer to Example 3 above, and use the default setup to output the IIC protocol

timing sequence as shown in the diagram below:

SCLK

SDA

Start Stop

Figure 3-5 Time sequence of IIC protocol

From the above Figure 3-5, where SDA jumps from high to low when SCLK=1

indicates the “start” of the data output, and then; Address (0x00), Write

operation (0), response bit (High Z), 1 Byte data (01 code pattern), response

bit (High Z). The data output stops when SDA jumps from low to high when

SCLK=1.

2. In PO protocol, set “D0” as SCLK, “D1” as SDA and the code pattern as “User”.

Through editing the data in the user space, it can generate an IIC protocol

digital waveform.

1) First the SCLK data, because SDA jumps when SCLK transits from high or

low, SCLK data should not be set as 010101…, and it should be

001100110011…;

2) Since the IIC protocol has “high Z” output, the Mask Channel and the

Tri-state Channel should be set; D1 is the Tri-state Channel for data

output, and D2 is the Mask Channel.

3) Data in D0 and D1 can be edited with reference to Figure 3-5. While D2

is the Mask Channel, setting the corresponding bits of D1 (Tri-state

Channel) to “1” will produce a High Z output; and the rest “0”.

below:

Data Overflow

1. Data length upper limit** Bytes=**k Bytes

RS232: Data length upper limit 35840 Bytes=35k Bytes

SPI: Data length upper limit 40960 Bytes=40k Bytes

IIC: Data length upper limit 10240 Bytes=10k Bytes

PO: Data length upper limit 131072 Bytes=128k Bytes

When user‟s setting exceeds limit, the system will automatically adjust it to the

corresponding upper limit.

2. Data length lower limit 1 Byte

The data length lower limit is 1 Byte for all the protocols. When user‟s setting is

lower than 1 Byte, the system will automatically adjust it to be 1 Byte.

3. ** Mbps

It denotes the transmission rate upper limit.

RS232: 60 Mbps

SPI: 60 Mbps

IIC: 30 Mbps

PO: 100Mbps

When user‟s setting exceeds limit, the system will automatically adjust it to the

corresponding upper limit.

4. 1bps

It denotes the transmission rate lower limit.

The transmission rate lower limit is 1 bps for all the protocols. When user‟s

setting is lower than 1 bps, the system will automatically adjust it to be 1 bps.

RS232: 2.0V or -4.5V according to the instrument type.


Digital voltage:

RS232: Off

SPI、IIC、PO: 1.4V.

When the set voltage exceeds the lower limit, the system will automatically

adjust it to the corresponding lower limit.

9. Data Number per frame Upper limit 3 Byte

In SPI protocol setting, the upper limit of transmission data per frame is 3 Byte,

if the specified value is higher than 3 Byte, the system will automatically adjust

it to be 3 Byte.

Troubleshooting

1. If digital module does not work after DG3000 powering up, please

follow the steps below:

(1) Turn off the instrument, check if the connection cable is correctly connected.

(2) Turn on the instrument, check if the Digit-Modu option has set to be

“Power-On”.

(3) If it does not work correctly, contact RIGOL for our service.

2. If all the settings are correct, but no waveforms output, please follow

the steps below:

(1) Check if the SMB-to-SMA RF coaxial line or logic analyzer testing lines you are

using are correctly connected.

(2) Set the Power On option to be Last when all the above steps have been

finished.

(3) Restart the instrument.
